Header Coating - Wrap
 

What it the concensus on header coatings and wraps?

Finally got the car on the dyno today.
Headers glowing orange.

Lots of heat into the intakes and firewall.

My headers are stainless steel. 20b PP NA full race motor.

Is there a header coating or wrap that keeps the heat in?
Does it shorten the header life?

I always do both, first ceramic coating then wrap it. And no it doesn't shorten the header life.
